Tohoku Univ. Technology：Quantum bit / Quantum sensor material using SiO2：T24-052
Can be produced at low cost. Proven write operation.
Nitrogen-vacancy center (NV center) in diamond satisfies the characteristics required for qubits, and expected to be applied to quantum computers and quantum sensors. Other candidate materials are divacancy centers (VV centers) in SiC and Ce-implanted Yttrium Aluminum Garnet (YAG). However, the problem with all of these materials is the high cost of raw materials, and it is expected to be difficult to scale up. The present invention demonstrates that light emitting centers (Ce3+) can be formed in Ce implanted SiO2 or MgAl2O4 substrates. Optically Detected Magnetic Resonance (ODMR) measurements demonstrate the feasibility of write operations in quantum dots. It is possible to realize a quantum bit / quantum sensor at low cost.

Company information
The revenue generated from technology transfer is reinvested into universities and researchers as new research funding, which is used to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will actively promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by concluding basic technology transfer agreements with the following universities (as of June 1, 2025): - Tohoku University - Hirosaki University - Iwate University - Akita University - Fukushima University - Yamagata University - Tohoku Gakuin University - Iwate Medical University - Fukushima Medical University - Aizu University - Miyagi University - Hokkaido University - Muroran Institute of Technology - Showa Medical University
